It takes years to have the optimum conditions to cause an avalanche for research purposes. Controlled blasts done at a test site of Vallée de la Sionne will help scientists further model this phenomenon. The Swiss Institute for Snow and Avalanche Research, SLF, has been around since the 1930s. One of their main research fields is to provide new measures to be better prepared for avalanches.
